Two advantages of well irrigation are-

  2. By the use of pumps and tubewells, water can be lifted even from great depths.

Two disadvantages of well irrigation are-

  1. Wells depend on underground water resources whose distribution varies from region to region.
  2. The traditional wells dry up due to over withdrawal of the ground water and lowering of the water table.
